Approved by Exelon Board of Directors 06-27-06



MESSAGE FROM THE CEO

Our Vision is to become the very best electric and gas company in the United States. To realize our Vision, we must commit ourselves not only to safety, accountability, and continuous improvement, but to the highest
ethical standards.

The business prospects of our Company are excellent, and the foundation that we build on is very strong. That foundation comes from the
people of Exelon, and from the service that we have provided to our customers, communities and employees. We are regarded as honest and caring, but disciplined, business people who are involved in providing essential services to major urban
populations. We can be successful only if we employ an engaged workforce that best serves our diverse communities. And to meet the high standards set by our Company, we must conduct our operations safely and be leaders in developing solutions to our
industrys environmental challenges.

Because our business involves services that are central to citizens in their every day lives and necessary for
businesses to operate productively in the nations economy, our operations are closely reviewed by governmental officials at the local, county, state and national level. Likewise, individuals and institutions have invested billions of dollars
in our business with the expectation that we will honestly and productively use this capital to profitably operate our company and increase shareholder value.

We will be successful if we operate our Company, employ our people and finance our business in accordance with the highest ethical standards and with the law. We will destroy shareholder value if we do not. Our Exelon Code of Conduct
provides the outline of what is expected of all of us to meet our important obligations, and gives us resources to understand these requirements and live up to them.

Please read this Code carefully, and ask your supervisor or the Ethics and Compliance Office if you have any questions. Our Companys success depends on each of us living up to these standards. I commit to you
that I will do so. I expect no less from each and every one of you.

John W. Rowe

INTRODUCTION

Using This Guide

The success of Exelon Corporation, including its subsidiaries (Exelon or the Company), is
dependent on all of us conducting our activities in accordance with the highest ethical standards and applicable law. This Exelon Code of Business Conduct (Code) reflects our core value of integrity and is the statement of our required
behavioral standards. The Code may, in some instances, set performance levels or expectations that are more stringent than required by law. They are nonetheless required. Exelon recognizes that such enhanced performance fosters compliance with law
and provides a platform for our Company to be successful in the eyes of our customers, employees and investors.

The Code does not cover all situations
where questions of ethics may arise. That would be virtually impossible to do. It enables you to identify situations that may raise ethical and legal issues, and is designed to help you learn what to do whenever you have a question or concern about
what conduct the Company expects from you. All employees are held accountable for following the Code and it is important that you take the time to read it from cover to cover.

To assist with your understanding, described below is the purpose of each section of the Code.



| | 1. | The message from the CEO explains the importance of Exelons commitment to the Companys core value of integrity.
| | -- | -----------------------------------------------------------------------------------------------------------------



| | 2. | The Introduction explains the accountability that all employees have for complying with the Companys policies and for raising concerns about possible violations of law or
policy.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | The Exelon ethical and legal business standards follow the Introduction. For each standard there is an Overview, which generally describes the standard, and the
Main Obligations which are the core requirements under each standard. In some cases, there are also examples of Things to Watch Out For, which are circumstances that should alert you to a potential ethical or legal issue.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | For each standard, there are Exelon policies that provide additional detail. The complete and latest text of the related Exelon policies are found on the Exelon Intranet Website.
You should read the policies and talk to your manager to understand how the ethics standards and supporting Company policies apply to your job.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | The Exelon Ethics Principles, stated below, are the framework from which the behavioral standards described in the Code are developed. They are your guideposts for understanding
what acting with integrity looks like, in other words, how the Company expects that each employee will, at all times, conduct the Companys business.

Political Contributions and Lobbying

Personal Contributions

Employees have the right to participate in the political process and to engage in political
activities of their own choosing. While involved in personal civic and political affairs, employees must make clear that their views and actions are their own, and not those of Exelon. If you have questions regarding personal political contributions
or other personal political activity, seek guidance from the Legal Department, Government Affairs, or the Ethics and Compliance Office.

Main
Obligations



| |  |  | Employees may not solicit contributions from other employees for personal political purposes on Company time and may not require other employees, including
secretarial or other support staff, to perform tasks in support of an employee's personal political activities
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Employees may use an insignificant amount of Company resources, such as phones, fax machines or office supplies for their personal political purposes, where state
law permits
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Employees may make personal political contributions, but will not be reimbursed for such contributions by the Company
| | - |  | ---------------------------------------------------------------------------------------------------------------------

Corporate Contributions and Lobbying

Federal law places limits on a
corporations ability to participate fully in the political process, especially by imposing prohibitions on corporations from making contributions of any kind to a candidate, political party, or political committee in connection with a federal
election. Some states impose similar restrictions on making corporate contributions and conducting activities to support state or local candidates. Certain limited activities, including political action committees and lobbying, are allowed and
should be coordinated by Governmental Affairs. If you have questions regarding corporate contributions or lobbying, seek guidance from the Legal Department, Government Affairs, or the Ethics and Compliance Office.

contributions and conducting activities to support state or local candidates or campaigns should be reviewed in advance with Government Affairs, the Legal Department or the Ethics and Compliance Office
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

dealing or tipping.

The SEC has established a code of professional conduct applicable to attorneys who advise the Company on matters that may relate to the Companys SEC filings. The

Affiliate Non-discrimination

The Federal Energy Regulatory Commission and the state utility commissions in New Jersey, Pennsylvania and Illinois have adopted regulations governing the business
dealings between utility subsidiaries of Exelon Energy Delivery Company (collectively referred to as EED) and its affiliates to ensure that resources and assets of the regulated businesses of the Company are not used to subsidize or give
an unfair advantage to other lines of the Companys business. Employees must comply with all of these regulations and similar Tariff provisions applicable to business conducted by the utilities. Some examples of these include: the FERC
Standards of Conduct, the Pennsylvania Code of Conduct, the Illinois Affiliate Non-Discrimination Rules and the New Jersey Affiliate Standards Rules.

Antitrust and Unfair Competition

Antitrust laws promote, preserve and protect competition and are a critical part of the environment in which Exelon operates. Violations of competition laws may expose
Exelon and individual employees to criminal and or civil liability and associated penalties, including monetary damages, fines and even imprisonment.

Antitrust laws are complex. They generally prohibit joint action that restrains competition, as well as improper unilateral action that either propels one competitor into a monopoly position in the market or seriously threatens to do so.
Other aspects of the antitrust laws prohibit certain types of discrimination in pricing and unfair trade practices. Employees who interact with customers, competitors or suppliers and anyone who believes that he or she is dealing with a situation
that might have antitrust implications, should consult with the Legal Department or the Ethics and Compliance Office.

Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act (FCPA) has two main provisions. The anti-bribery provision makes it a crime to promise or give anything of value to foreign
governmental or political officials or their agents to obtain or retain business, obtain any improper advantage or otherwise influence their judgment in the performance of official duties.

The FCPA also requires that publicly held companies, like Exelon, maintain accurate books, records and accounts and devise a system of internal accounting controls
sufficient to provide reasonable assurance that, among other things, the Companys books and records fairly and accurately reflect business activities and transactions. It is Exelon policy to present financial statements fairly and accurately
and in accordance with generally accepted accounting principles.

Sales and Marketing Competitive Practices

While information about our competitors is a valuable asset, federal law and our Code require that we obtain this information legally.

CODE OF CONDUCT PROCESSES AND RESOURCES

Waivers

A waiver of any
provision of the Code will be made only in exceptional circumstances for substantial cause. Requests for waivers must be submitted to the Corporate General Counsel, or his or her designee, for review and resolution. Any request for a waiver by any
Director or Executive Officer must be submitted to the Board of Directors or a Board Committee. All waivers will be reported to the Exelon Ethics and Compliance Council. In addition, any waiver of a provision in the Code for any Director or
Executive Officer will be disclosed to stockholders.

Certification of Compliance

Directors and non-represented employees and, in certain instances, independent contractors must complete each year a certification of compliance questionnaire. A
completed certification questionnaire is a condition of employment for all non-represented employees. Directors will certify compliance with the Code in connection with the completion of their annual questionnaire.

Independent contractors required to complete the questionnaire are those who have access to Confidential Information, as defined in the Code, or those engaged in
contract administration activities for Exelon such as verification of services and review and approval of invoices. The certification questionnaire is an acknowledgement of understanding and a self-assessment of Code compliance.

The certification questionnaire is administered on a confidential basis by the Ethics and Compliance Office. Exceptions that identify suspected violations of the law or
this Code will be managed in accordance with the provisions stated below in Reporting and Investigating Violations.

Reporting and Investigating Violations

Exelons success in achieving legal and ethical compliance depends on each employee not
only conducting his or her responsibilities in accordance with the law and the Code, but also by reporting matters that raise compliance or ethics issues.

Employees must report potential violations of the law or the Code by using one of the resources described in this section. Employees may be disciplined up to and including discharge for the failure to report a Code violation where they have
a reasonable basis to know that a violation is occurring or has occurred.Employees who knowingly submit false reports will be subject to disciplinary action. If an employee self-reports wrongdoing, it will be a factor considered by
management in connection with any discipline imposed for a violation of the law or the Code.

Approved by Exelon Board of Directors 06-27-06



All reports alleging violations of the law or the Code will be treated confidentially to the extent possible under
the circumstances. A prompt, thorough and independent investigation will be conducted of reported concerns. Employees are required to cooperate in any investigation of a compliance or ethics concern. Reported concerns regarding accounting, internal
accounting controls or auditing matters will be reported to the Audit Committee of Exelons Board of Directors.

If an investigation discloses the
need for corrective action, Exelon will implement appropriate corrective action to prevent recurrence.

The Ethics
and Compliance Office

Because compliance and high standards of ethical behavior are important to the Company, employees must have access to
additional guidance from a knowledgeable person when circumstances require. Exelon is committed to providing employees with the resources necessary to help them understand the Code, resolve compliance and ethics questions and report any compliance
or ethics concerns. In this regard, Exelon employees have several options.

Managers and supervisors are an initial source of guidance for employees and an
appropriate channel for questions or reporting compliance or ethics concerns. Each employee is encouraged to contact his or her manager or supervisor to discuss issues of interpretation or to report concerns with respect to compliance with the law
or the Code.

The Ethics and Compliance Office is another avenue for seeking guidance on Code interpretation or reporting concerns. The office reports to
the Corporate Secretary and its staff includes an Associate General Counsel accountable for administering the ethics and compliance program. The Ethics and Compliance staff may be reached by phone, e-mail, regular mail, or in person. Contacts may be
made anonymously. All contacts will be treated confidentially to the fullest extent possible. Reports to the Ethics and Compliance Office will be handled promptly, thoroughly, fairly, and discreetly.

Other avenues for guidance and reporting concerns in their respective areas are: Human Resources, Legal, Corporate Security, Internal Audit and Environment, Health and
Safety.

Exelon employees may also contact the Exelon Help Line at 1-800-23-ETHIC, which is further described below.

CONCLUSION

Ethical Decision Making

One of
the primary goals of the Code is to enable employees to make ethical business decisions. The Code establishes a set of common expectations for behavior in areas that are vital to the Companys reputation and that pose ethical or legal concerns.

Employees may find it helpful to ask the following questions before taking action in specific situations:



| |  |  | Is your action honest in every respect?
| | - |  | ---------------------------------------



| |  |  | Will your action comply with the intent and purpose of the Code?
| | - |  | ----------------------------------------------------------------



| |  |  | Does it conform to Exelons policy?
| | - |  | -----------------------------------



| |  |  | Could you defend your action in front of supervisors, fellow employees, the general public and your family?
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Do you feel comfortable taking the action?
| | - |  | ------------------------------------------

In
judging the appropriateness of any action, employees should be able to answer yes to each of these questions. If you are still unsure or uncomfortable with your course of action, please seek assistance.

The Company relies on the personal judgment and thoughtful behavior of each employee in conducting Company business. Ultimately, employees are personally accountable for
their decisions and should discuss ethical questions with a supervisor, manager, or any of the other resources identified in this Code, or call the Ethics and Compliance Office Help Line at 1-800-23-ETHIC. Employees who feel uncomfortable discussing
ethical questions with a supervisor or manager are encouraged to contact the Ethics and Compliance Office or call the Help Line at 1-800-23-ETHIC.

Accountability

Each employee is accountable for understanding and complying with the Code and compliance is a
condition of employment. Managers have the additional accountability to create an environment that encourages ethical conduct and a commitment to compliance with the law.



| |  |  | Managers, in collaboration with the Ethics and Compliance Office, are accountable for the following
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Knowing and communicating the laws and regulations that affect their respective areas of operation
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | Assessing the potential for unethical or illegal conduct in their respective areas of operation and taking action to mitigate it

regulators, investors and suppliers, expect it, and our success depends on it.

*****************

The Code is not a contract of employment and is not intended to create any contractual obligations on the part of Exelon. It does not alter the existing at-will
employment relationship between Exelon and its employees. Labor organizations that represent employees have been placed on notice that the Code is included in the work rules applicable to their members.
